Pivot values in specific order

I have a dataframe where I would like to pivot my data to fit a specific format, making sure the dates are consecutive.

Data

ID  Q122_c_en   Q122con_s   Q222_c_en   Q222con_s Q322_c_en Q322con_s Q422_c_en Q422con_s
AA  900         89          1000        90        1200      92        1000      90
BB  1000        10          1000        20        1100      25        1300      30

Desired

ID  Date    con_en  con_s   
AA  Q122    900     89  
AA  Q222    1000    90  
AA  Q322    1200    92  
AA  Q422    1000    90  
BB  Q122    1000    10  
BB  Q222    1000    20  
BB  Q322    1100    25  
BB  Q422    1300    30

Doing

df.pivot(index="ID", columns="Date", values=["con_en", "con_s"])

I am using pivot, however, the format does not reflect the desired above format. Any suggestion is appreciated.

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...

Sorting large arrays of big numeric stings

I was solving bigSorting() problem from hackerrank: Consider an array of numeric strings where each string is a positive number with anywhere from to digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array. I know it works as follows: def bigSorting(unsorted): return sorted(unsorted, key=int) But I didnt guess this approach earlier. Initially I tried below: def bigSorting(unsorted): int_unsorted = [int(i) for i in unsorted] int_sorted = sorted(int_unsorted) return [str(i) for i in int_sorted] However, for some of the test cases, it was showing time limit exceeded. Why is it so? PS: I dont know exactly what those test cases were as hacker rank does not reveal all test cases. source https://stackoverflow.com/questions/73007397/sorting-large-arrays-of-big-numeric-stings
